Working Memory Model

Question 1

Who created he working memory model?

Answer 1

Baddeley & Hitch

Question 2

Working memory model

Answer 2

👇 Central executive < 👇
Visuo-spatial 👇 Phonological
Sketchpad 👆 loop
Episodic buffer
👆
👇
Long term memory

Question 3

What is the central executive?

Answer 3

•Controller of the working memory
•decides which sub-system the incoming memory/data will go to
•completes logic and reasoning
•

Question 4

What is the phonological loop?

Answer 4

Processes sound
Coding is acoustic
Short capacity 1.5-2 seconds

Question 5

What are the 2 parts of of the phonological loop?

Answer 5

Phonological store- auditory memory
Articulately rehearsal process- let’s you imagine the sound of a word as its read/ inner voice

Question 6

What did Baddeley’s word length experiment show?

Answer 6

There are fewer longer words able to be stored in the stm
Anything that takes longer than 2 seconds to say with your inner voice will be forgotten

Question 7

Viuo-spatial sketchpad

Answer 7

Processes visual data
Coding is visual
Can store 3-4 objects

Question 8

What are the 2 parts of the VSS

Answer 8

Visual cache-stores visual cache
Inner scribe- records arrangements of objects

Question 9

What is the Episodic Buffer

Answer 9

Temporary store for information
Integrates visual, spatial, verbal information and LTM together
Added in 2000
Reduce order being muddled

Question 10

Strength WMM-Dual task evidence

Answer 10

Baddeley et Al 1975 showed existence of vss
Track moving light with a pointer
Given 1 of 2 tasks:
1- describe all angles of F
2- perform a verbal task
Harder to describe f and trace as both VSS
Verbal task and tracing is easier as one uses VSS and phonological loop

Question 11

Strength WMM- Clinical Evidence

Answer 11

K.F- Shallice and Warrington 1970
Did worse on digit test when numbers read to him compared to when he read the numbers himself
Suggests he damaged his phonological loop
Rest his working memory was in tact
Supports wmm

Question 12

Limitation WMM- Central Executive

Answer 12

Its not fully understood
Baddeley says “it’s the most important but least understood the component”
Some psychologists argue it’s more than one component
Me need more information

Question 13

Limitations WMM- Artificial material

Answer 13

Mostly supported by lab studies
Use artificial material like word lists
Rare to be asked numbers letters and digits in real life
Represent memory in a lab not real life
